Proper Layout and Component Selection Controls EMI News & Analysis 9/30/2003 Post a comment Understanding the physics of voltage-regulator topologies is important when designing power systems for EMI and EMC compliance. In particular, the physical principles behind switching regulators (buck, boost, flyback, and SEPIC topologies) guide component choice, magnetics design, and PC board layout. Parasitic elements such as leakage inductance, ESR, and ESL are significant when optimizing circuit performance.
